Welp, my dad and I definitely need to do some work with his Darwin. Came home to find the thermostat beeping at me for the second time in two days, so opened to take a look and found it was under her kriter krumble - reached in, not thinking about it, to move it out in the open again and she tagged me from her shelf... Not completely sure if it was a defence bite or a food bite that didn't latch on cause my hand moved when she hit it. But we've definitely got to get her to calm down a bit about people reaching, pry made a few mistakes in terms that she usually sees movement, the door opening and such as feeding time - also think maybe she's feeling hungry despite getting two adult rats at a time these days (she's about 5 years old, around 2.7 metres). Sorta already feel like part of what needs doing is working to break the association she has with those things mentioned above being related near solely to food. She's also somewhat cage defensive since most bites we've coped have been the 'mouth wide open, hit, retract' type. Any tips would be gratefully received.
